First off this is a BL series, meaning 'boy's love.' To what extent is yet to be fully determined. Fair warning.  The world as it once was laid in shambles. Humankind faced extinction. The dead walked the earth. All things unnatural awoken, and as humans were nearly wiped out from the planet, they were saved by the discovery of strange and profound superhuman abilities.  However, the end always brought out the worst. The worst monsters, be they human or not.   Yet, not all those still alive chose to live like monsters.  Some wish to live peacefully by themselves in a destroy world teaming with danger.
